The basic objective is that viewer should get intuition of the idea behind Pi and how it was evaluated first, many years ago. How can we start from a simple polygon (triangle) and using it getting the value of such an amazing transcendental number "Pi", by increasing the sides of polygon to a really large number. The main tool used to make this is basic geometry and some elementary trigonometry identities and combining all of these in manim to get a really satisfying animation which gives the idea of Pi and how it can be evaluated
